LUBRICATING MEo ANIsM'ro a INTERNAL-COMBUSTION ENGINES. I

Application filed. April 10, 1922. Serial No. 551,218

To whom it may concern Beit known that I, J AMES W. Hanowion', a citizen of the United States, residing at Humbird, in the county of, Clark and State of Wisconsin, have invented certain newand useful Improvements in aLubricating Mechanism for Internal-Combustion v Engines; and I jdo'h'ereby declare the following to be afull, clear and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. v *This invention relates to a lubricating mechanism for internal combustion engines. It is aimed to provide means whereby the transmission of an automobile or the like,

particularly the Ford type, may havefthe lubricant circulate without the aid of a pump in order to be subject tothe cooling influenceof the atmosphere, and accordingly such a means as will be inexpensiveas well as durable and eflicient."

Another vobject is to provide an attachment for the transmission casing in such anengine which will consist of a tank and conduits connecting the transmission and the tank and disposed at different elevations. Additional objects and advantages will become apparent froma consideration of the description following taken in connection with accompanying drawings illustrating one practicalembodiment.

In said drawings o I Figure 1 is a view in perspective of aportion-of 'an'engin'e of the internal combustion t pe' having my improvement associated therewith, and Figure 2' is a side elevation of the same. I d V, 'In'said drawings, at A an internal combustion engine is conventionally shown which has its transmission case at B, the lower portion of which at G serves. as an oil or lubricant reservoir in which movable parts of the engineor motor operate and splash the lubricant to diflerent parts to be lllbI'I-r cated. This transmission casing may have pet cock valves at D, arranged at dilierent levels as in the Ford'motor and adapted to be opened to determine thequantity of oil contained in the reservoir'C.

In carrying outmy invention, atank or receptacle'of suitable size and shape isprovlded at 10 and is secured to any suitable part ofthe propelling engine or adjacent, structure of an automobile. In actual practice, I'find a tank 10 adapted to contain about one gallon of oil to work efficiently with aF-ord motor; 7 l1 .A pipe-or conduit 11;]e-xtends from the tank 10 to the transmission case B, preferably being secured thereto and communicating with its interior'intermediate the pet cocks D. Another oil conduit or pipe is employed at 12 which coinmunicateswith the interior of the transmission casingv-D adjacent the top and with the reservoirrG, as at one side thereof. 7 v

In operation,sufiicient'oil'or lubricant is supplied to the transmission case B tofill it to the desired level and to fill the tank 10. As the motor operates, the traveling parts within the transmission case B will splash oil in the reservoir G into the pipe 12' which thereupon flows intothe tank 10 and from the tank 10throughthe pipe .or conduit 11 back to the transmission case. In this way,

the oil is efiectively circulated and subjected .to the cooling influence of the atmosphere. The circulation of the oiljalso is insured by the agitation due to the pressure produced within the engine through the operation of its pistons and the vibration and jo-lting of the automobile as a whole. I t As merely one practical embodiment has been illustrated and described,"it is to be understood that changes; in the details may be resortedto providedthey fall within the spiritandsoope. I claim as my invention 7 V V In an internal combustion engine, in comebination with a case in which lubricant is" splashed through operation of the engine, an auxiliary lubricant tank transversely disposed exteriorlyofthe case in compact relation to the engine and under the latter and offset from and substantially out of contact with the caseso asto be subject to the cooling influence of the atmosphere substantially completely about its exterior, an elongated conduit exteriorly of the case which splash- T1070 I A ing lubricant enters at a relatively high causing the oil to travel in a relatively fine point, said conduit being in communication stream to assist in cooling it. 10 with the tank above the base of the latter, In testimony whereof I affix my signature and an elongated return pipe in communicain presence of two witnesses.
